如何发布照片。 iOS Facebook SDK 3.1

本文介绍了如何发布照片。 iOS Facebook SDK 3.1的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我需要在我的墙上发布一张照片。图片是在我的iPad应用程序中生成的。

解决方案

这是我找到的最简单的方法

- （void）postImageToFB：（UIImage *）image { NSData * imageData = UIImageJPEGRepresentation（image，90）; NSMutableDictionary * params = [NSMutableDictionary dictionaryWithObjectsAndKeys： @这是我的绘图！，@message， imageData，@source， nil]; [FBRequestConnection startWithGraphPath：@me / photos参数：params HTTPMethod：@POST completionHandler：^（FBRequestConnection * connection，id result， NSError * error）{ }]; }

如果要在朋友的墙上张贴，请更改 @我/照片 by @[friendID] / photos

然后，请求发布权限并调用方法

if（[FBSession.activeSession.permissions indexOfObject：@publish_stream ] == NSNotFound） { //在会话中找不到权限，请求 [FBSession.activeSession reauthorizeWithPublishPermissions：[NSArray arrayWithObject：@publish_stream] defaultAudience： FBSessionDefaultAudienceFriends completionHandler：^（FBSession * session，NSError * error） { //如果权限授予，发布故事 if（！error）[self postImageToFB：currentDrawing] ; }]; } //如果存在权限，发布故事 else [self postImageToFB：currentDrawing];

如果不存在，将创建一个[App Name] Photos相册

它对我有用！

I needed to publish a picture on my wall. The pic is generated in my iPad app.

解决方案

This is the simplest way I've found

- (void) postImageToFB:(UIImage*)image { NSData* imageData = UIImageJPEGRepresentation(image, 90); NSMutableDictionary * params = [NSMutableDictionary dictionaryWithObjectsAndKeys: @"This is my drawing!", @"message", imageData, @"source", nil]; [FBRequestConnection startWithGraphPath:@"me/photos" parameters:params HTTPMethod:@"POST" completionHandler:^(FBRequestConnection *connection, id result, NSError *error) { }]; }

if you want to post on a friend's wall, change @"me/photos" by @"[friendID]/photos"

Then, ask for permissions to publish and call the method

if ([FBSession.activeSession.permissions indexOfObject:@"publish_stream"] == NSNotFound) { // No permissions found in session, ask for it [FBSession.activeSession reauthorizeWithPublishPermissions:[NSArray arrayWithObject:@"publish_stream"] defaultAudience:FBSessionDefaultAudienceFriends completionHandler:^(FBSession *session, NSError *error) { // If permissions granted, publish the story if (!error) [self postImageToFB:currentDrawing]; }]; } // If permissions present, publish the story else [self postImageToFB:currentDrawing];

An "[App Name] Photos" album will be created, if doesn't exist

It does work for me!
